Fitspy (A generic tool to fit spectra in python)

Fitspy

Fitspy is a generic tool dedicated to fit spectra in python.

Its GUI aims to be as simple and intuitive as possible.

Processed spectra may be independent of each other or may result from 2D-maps acquisitions.

Example of a fitspy 2D-map frame interacting with the main GUI

The fitting algorithm has multiprocessing capabilities and relies on the lmfit library.
Bounds and constraints can be set on each peaks models parameter.

The peak models considered in fitspy are :

• Gaussian
• Lorentzian
• Asymetric Gaussian
• Asymetric Lorentzian
• Pseudovoigt

A constant, linear, parabolic, gaussian or exponential background can also be added in the fitting.

All actions allowed with the GUI can be easily executed in script mode (see examples here).

All users instructions (baseline definition and removal, peaks definition, parameters constraints, ...) can be saved in a 'fitspy' model and replayed as is or applied to other new spectra.
